| 中文摘要 | The effect of Sr doping on the transport and snag netism properties of charge/orbital-ordered Nd(0.55)Ca(0.45)MnO(3) is investigated. A low temperature phase transition from a charge/orbital ordered insulator to a ferromagnetic metal was founded in the Nd(0.55)(Ca(1-x)Sr(x))(0.45)MnO(3) samples. The ground state is the charge/orbital ordered insulator at x < 0.2, while for x > 0.3 it changes to a ferromagnetic metal. The resistivities of the samples exhibit almost ideal percolation behavior with a percolation threshold of 0.3. Therefore, this system shows an intricate competition between metallic ferromagnetism and charge/orbital ordered insulator and the percolation behavior demonstrates that the relative volumes of ferromagnetic phase and charge/orbital phases changes with the doping content x and temperature. |
